Abstract

A method for controlling an output power of a fuel cell is disclosed. A DC converter and a fuel cell are provided, and a voltage input end of the DC converter is connected to a voltage output end of the fuel cell. The DC converter is used to convert an output voltage of the fuel cell into a regular output voltage. The DC converter is also used to retain a voltage of the voltage input end of the DC converter within a predetermined range, and thereby an output voltage of the fuel cell is maintained within a predetermined range. The predetermined range of the voltage is set according to a number of membrane electrode assemblies in the fuel cell and a voltage of the membrane electrode assemblies generated in an extent of optimal power.
